THE IUCN RED LIST OF THREATENED SPECIES™ Taxonomy Kingdom Phylum Class Order Family Animalia Chordata Reptilia Squamata Lacertidae Taxon Name: Archaeolacerta bedriagae (Camerano, 1885) Synonym(s): • Lacerta bedriagae Common Name(s): • English: Bedriaga's Rock Lizard • French: Lezard De Bedriaga Taxonomic Notes: This species is traditionally included in the genus Lacerta, but it is not closely related to Lacerta sensu stricto (Arnold 1989; Fu 1998, 2000, Harris et al. 1998, Carranza et al. 2004). As it is the type species of Archaeolacerta, this genus is available for it (following Arribas (1998), Mayer and Arribas (2003) and Crochet and Dubois [2004]). This species is the only representative of Archaeolacerta. There are three recognized subspecies: the nominate in Corsica, A.b. sardoa from central Sardinia, and A.b. paessleri in northern Sardinia (perhaps a synonym of sardoa), but their validity seems not confirmed by genetic studies (M. Bologna in litt.). Assessment Information Red List Category & Criteria: Near Threatened ver 3.1 Year Published: 2009 Date Assessed: December 14, 2008 Justification: Archaeolacerta bedragae is listed as Near Threatened. Its Extent of Occurrence is less than 20,000 km2; on Sardinia its distribution is severely fragmented and there is continuing decline in the extent and quality of its forest habitat, but on Corsica it is not considered to be severely fragmented or declining. Previously Published Red List Assessments 2006 – Vulnerable (VU) Geographic Range Range Description: This species occurs in rocky areas on the islands of Corsica (France) and Sardinia (Italy) where it has a very fragmented range. In Sardinia it has a very fragmented range. On these two large islands it occurs mainly from 550 to 2,550 m asl, but there are a few coastal populations, including in northern Sardinia and western and southern Corsica. It occurs on several smaller islands, including Foloca Island (France), © The IUCN Red List of Threatened Species: Archaeolacerta bedriagae – published in 2009. 1 http://dx.doi.org/10.2305/IUCN.UK.2009.RLTS.T61468A12490617.en the Maddalena Archipelago and the Isola Rossa di Trinita' d'Agulto (Italy). On smaller islands it occurs down to sea-level.

At lower elevations and in Sardinia it occurs in very small areas, although large populations can be found locally. Current Population Trend: Decreasing Habitat and Ecology (see Appendix for additional information) This is typically a rock dwelling lizard, living on cliffs and open rocky areas (e.g. sparsely vegetated islets). It is also found in open woodland and scrubland. It can occur in semi-shaded areas close to streams. The females lay three to six eggs. Systems: Terrestrial Threats (see Appendix for additional information) Populations in the lowlands of Corsica are vulnerable because of the genetic isolation of many populations. Populations on both islands are threatened by the development of the tourist industry. Sardinian subspecies are vulnerable because they are severely fragmented and have an extremely small area of occupancy. Conservation Actions (see Appendix for additional information) Populations in Sardinia may be more sensitive to the threats and populations are strictly protected. This species is listed on Annex III of the Bern Convention, Annex IV of the EC Habitats Directive, and is protected by national and regional legislation in both countries. It occurs in several protected areas. Credits Assessor(s): Claudia Corti, Marc Cheylan, Roberto Sindaco, Antonio Romano, Patrick Haffner Reviewer(s): Cox, N. and Temple, H.J.
